解析一个html表格后,我能够获得表格的第一行作为Nokogiri元素。访问Nokogiri元素子元素
2.2.1 :041 > pp content[1]; nil
#(Element:0x3feee917d1e0 {
name = "tr",
children = [
#(Element:0x3feee917cfd8 {
name = "td",
attributes = [
#(Attr:0x3feee917cf74 { name = "valign", value = "top" })],
children = [
#(Element:0x3feee917ca60 {
name = "a",
attributes = [
#(Attr:0x3feee917c9fc {
name = "href",
value = "/cgi-bin/own-disp?action=getowner&CIK=0001513362"
})],
children = [ #(Text "Maestri Luca")]
})]
}),
#(Text "\n"),
#(Element:0x3feee917c150 {
name = "td",
children = [
#(Element:0x3feee917d794 {
name = "a",
attributes = [
#(Attr:0x3feee9179fb8 {
name = "href",
value = "/cgi-bin/browse-edgar?action=getcompany&CIK=0001513362"
})],
children = [ #(Text "0001513362")]
})]
}),
#(Text "\n"),
#(Element:0x3feee91796a8 {
name = "td",
children = [ #(Text "2016-09-04")]
}),
#(Text "\n"),
#(Element:0x3feee9179194 {
name = "td",
children = [ #(Text "officer: Senior Vice President, CFO")]
}),
#(Text "\n")]
})
=> nil
这是该行的内容:
马斯特里卢卡0001513362 2016年9月4日官:高级副总裁,CFO
我需要访问的姓名,号码,日期和Nokogiri元素的标题。这样做的
一种方法是如下:
2.2.1 :042 > pp content[1].text; nil
"Maestri Luca\n0001513362\n2016-09-04\nofficer: Senior Vice President, CFO\n"
不过,我正在寻找单独访问的元素,而不是作为一个长刺用换行符的一种方式。我该怎么做?
